Bearing Roller Turning, 55% Cost Reduced

Wind Turbine Bearing Industry

• High production cost: Original tooling costs remained high.
• Rapid insert wear: High roller hardness led to accelerated tool wear and increased usage costs.

A horizontal precision lathe equipped with PCBN cutting tools was used to complete roller outer diameter finishing in a single precision turning operation.

• Tool life: Increased by 5% compared with the previous tooling solution.
• Production efficiency: Maintained at the original level.
• Machining cost: Tool usage cost reduced by 55%.
• Customer feedback: “The new cutting tool solution improved the tool life and significantly reduced machining costs, achieving both cost optimization and machining quality improvement.”
